SPECIFICATION fermingp'ert ef Lettere Patent Ne. 412,552, dated octobere, 1889.

Application filed April 19 1889.

To all whom t may concern.-

Beit known that I, CHARLEsW. SLEEPER, a citizen of the United States,residing at Island Pond, in the county of Essex and State of Vermont,have invented a new and useful Can-Headin g Machine, of which thefollowing My invention relates to improvements in machinery for puttingoutside heads upon the bodies of tin cans; and the objects of myimprovements are, iirst, to provide a chuck to hold the heads and meansfor bringing the chuck up to the body; second, to provide means forplacing the heads in the said chuck; third, to provide a rest for thecanbodies and suitable iingers to press the tops of the bodies into theheads; fourth, to provide springs to slightly iiatten the bodies asfifth, to provide shields to prevent the upper other until they are inproperposition to put on. I accomplish these objects by means of themechanism illustrated in the accompanying drawings, in whichn Figure 1is a vertical section of the upper part of the machine, taken at line xx, Fig. 2. Fig. 2 is a front elevation of the upper partof machine,showing the position of parts at the moment that the heads are pressedupon the body. Fig. 3 is a side elevation of the machine, showing theposition of parts at the moment that the can-body is placed upon therest c. Fig. 4 is a front elevation of Fig. 3. Fig. 5 is a top view ofFig.4. Fig. 6 shows two positions of the chuck ct and carrier a5. Fig. 7is an enlarged detail of the chuck ot. Fig. 8 is a sectional view of thechuck et, taken at line ,ej e, Fig. 7. Figs. 9 and' 10 are enlargeddetails of the chuck et, showing the manner in which the spring-fingersctt operate upon the can-body. Fig. 11 is a side view of Fig.10. Fig. 12is a detail of the cam d3 and lower part of the cam-rod cl2. Fig. 13 isa section of the frame A and slide a, taken at line y y, Fig. 4.

Similarletters refer to similar parts throughout the several views.

The chuck a., Figs. 7 and S, is composed of a casting having a circularrecess cut into its face, and a semicircular piece et, iitted into thesaid recess, issecured to the casting by screws.

Serial No. 307,878. (No model.)

The said recess is open at the top to allow a Y head to slide into orout of the chuck, and the piece a3 is made to iit the outside diameterof the can-head. Two trunnions a a support the chuck in a suitablecarrier, and a guideroller ct2 is secured to a suitable projection uponthe side of the chuck. rlwo springfingers a4 a4 are secured to the pieceas.

The chucks ct ct are held by the trunnions a. a. in forked carriers a5a5, which are secured by pivot-screws to the slide a6, which is movedupon a dovetailed projection A upon the frame A. The slide 0.6 is movedby the facecam al, the said slide being provided with a roller to workin the recess in the said cam. The carriers a5 d5 are attached byconnectingstraps as ct8 to the levers a9 o9, which are operated by thecams al am upon the shaft au.

The guide-rollers a2 a2 work i-n guides am @12, which are secured to theframe A, and so arranged as to cause the chucks to turn upon theirtrunnions from a horizontal to a vertical position as the slide ctrises.

Fig. 4 shows the chucks in a horizontal position, and Fig. 2 shows themin vertical p0- sition. Two intermediate positions are shown in Fig. 6.

To place the heads in the chucks, I have provided brackets or tables bb, upon which the heads are placed one at a time, and two fingers b b',attached to levers b2 b2 and operated by cams h3 b3, push the heads fromthe tables b b into the chucks o, o..

T o support the can-bodies B in the machine, I have provided a rest c,upon which the bodies are placed one at'a time. Two fingers c c', thepoints of which are fitted to the circumference of the can-bodies, arepivoted upon screws to the projections A2 A2 upon the frame A, and serveas rests for the canbody when raised by the chucks o, ct. Shields d CZupon the arms d d', and operated by the cam-rods d2 cl2 from the cams d3d3, are arranged to drop between the can-heads and the can-body andgradually withdraw as the heads are brought into position to be pressedrhe machine is to be driven by a belt' applied to a pulley upon theshaft a, which is shown broken in Fig. 4.

In operation the heads e e are placed upon the tables b b,while thechucks are in the po IOO sition shown in Fig. 2, and when the chucksdescend to the position shown in Fig. 4 a canbody B is placed upon therest c. The iingers b b slide the heads from the tables b b 5 into thechucks a a, which are immediately raised by the slides a6 and carriersa5 0,5, and are gradually turned upon their trunnions as they rise bythe guides am cl2. (See Fig. 6.) The springs a4 a4 strike the can-bodyand 1o raise it until it touches the points of the fingers c c', and asthe chucks continue to rise the springs (being stiier than the can-body)press the sides of the body in, as shown in Fig. 9. The lower part ofthe can-body rests upon the lower part and inside of the head, theshields d d being between the heads and body to prevent their edges fromcatching together as the chucks rise. As the chucks rise, ,the heads areheld with their lower edges zo overlapping the body and their upperedges 'resting against the shields d d. The body is gradually pressedupward by the chucks un til the distance between the points ofintersection of the body with the yheads is less 2 5 than the width ofthe lingers c c. The shields being gradually withdrawn as the chucksrise, keep the points of intersection covered until they are covered bythe lingers c c', when they are entirely withdrawn and part 3o of bodybetween the points of intersection 1v is forced in by pressure againstthe ngers, and as soon as the outside of the canbody coincides with theinside of the heads the cams al@ al cause the carriers to approach 3 5each ,other and press the heads upon the body. The fingers c c arepivoted at their upper ends, so that they may be moved by the heads asthey are forced on. o

Ido not claim any especial manner o f plac- 40 ing the heads upon thetables or the bodies upon the rest. They may be placed by hand or by anyautomatic device.

What I claim as my invention, and desire to secure by Letters Patent,is-

i l. The combination, in a can-heading machine, of a chuck to hold acan-head, having a removable semicircular piece iitted to a recess inthe chuck and to the outside diameter of the can-head, two trunnions tosupport the 5o chuck, and with a guide-roller 0,2, with a guide am, toengage the said guide-roller, and means for supporting the chuck by itstrunnions, and means for moving the chuck in the guide a, substantiallyas described, and for the purpose set forth. 5 5

2. In a canheading machine, a chuck, substantially as described, to holda can-head, combined with a carriera/5, to support the chuck by itstrunnions, and with means for moving the carrier and chuck bothvertically 6c and horizontally, and with a guide a, to engage and actupon the roller a2, (carried by the chuck eccentric to its trunnions,)to cause the chuck to turn upon its trunnions from a horizontal toavertical position as the carrier rises, substantially as described, andfor the purpose set forth.

3. In a can-heading machine, a chuck, subtantially as described,acarrier @5,110 support the said chuck by its trunnions, the guide 7o am,arranged to engage the roller a2, carried by the chuck, and cause thesaid chuck to turn upon its trunnions as the carrier rises, and meansfor moving the carrier and the chuck both vertically and horizontally,combined with a rest c and lingers c c', substantially as described, tosupport acari-body, and with two spring-fingers a4 a, carried by thechuck and arranged to press upon and slightly iiatten the can-body asthe carrier rises, and with 8o a shield d, to enter between the can-headand the can-body to prevent their edges from striking each other, andwith means, substantially as described, for raising and lowering thesaid shield, substantially as described, and for the purpose set forth.

4. In a can-heading machine, the chuck a, carried by the carrier a5, andmeans, substantially as described, for moving the chuck and the carrierboth vertically and horizontally, 9o the guide a, to engage the rollera2, carried by the chuck, and cause the said chuck to turn upon itstrunnions from a horizontal to a vertical position as the carrier rises,combined with a table b, (upon which the canheads are placed,) soarranged as to be in the plane of the chuck d when the said chuck is inits lowest position, and with a finger b', to push the can-heads fromthetable into the chuck, and means, substantially as described, formoving the fingers b', substantially as described, and for the purposeset forth.
